- ! Adobe's licensed PostScript. Recently, RIPS reverse-engineered the
- ! eexec operator and now provides it to its licensees. Other clone

- !
- ! It is important to note that the eexec operator can be used to

- ! PostScript program or program fragment may be encrypted so it will

- !
- ! You will further note that eexec is not tied to fonts in any way.
- ! While eexec is mostly used to protect font data, it can be used to
- ! protect any PostScript code. It just so happens that Adobe's favorite
- ! thing to protect is font data. The eexec operator is also used to
- ! hide the methods for applying patches to the PostScript system and
- ! methods for gaining privileged access to protected procedures.
- !
- ! There is no gain in speed by encryption. In fact, there is a slight
- ! speed penalty resulting from decryption. The encrypted data is also
- ! twice as big as unencrypted data. This is compensated for in Adobe

- character no matter how coarse the grid is.
-
- ! Adobe's hinting system relies on regularizing (equalization) and
- ! straightening out the original character outline as much as possible
- ! when the font is created. Unfortunately this process of modifying the
- ! original font outlines for the sake of low resolution can badly
- ! distort the character from its original design. These distortions are
- ! visible when printing at high resolution. This system also places
- ! limitations on the placement of end points in the outline, again for
- ! the sake of the hinting system.
- !
- ! The new Fontographer hinting system (a subset of Nimbus-Q) places
- ! similar restrictions on the character outline. for instance, to make
- ! proper use of the hints, a character must be (re)drawn with curve end
- ! points at curve maximum/minimum X/Y extents. In order for strokes to
- ! be equalized to the same widths, they must be (re)drawn with exactly
- ! the same widths. Again, the shape of the character is ruled by the
- ! limitations of the hinting system.
- !
- ! The hinting system used by Kingsley/ATF in ATF Type Designer I* is
- ! fundamentally different. It does not require special placement of
- ! curve and end points in order to function. It also does not require
- ! modification of the original font outline to aid in grid fitting or
- ! stroke equalization. Once the outline has been created to the
- ! artist's satisfaction the hints for stroke equalization and grid
- ! fitting are added without any modification to the character outline.
- ! The net effect is that the Kingsley/ATF system does not sacrifice
- ! high-resolution quality while achieving low-resolution quality.
- !
- ! Character fill algorithms
- !
- ! The fill algorithm in PostScript tends to turn on too many pixels and
- ! make a character fatter and wider by one or two pixels. This is
- ! especially obvious in small sizes at low resolutions. Both Adobe and
- ! Kingsley/ATF compensate for this, thus keeping characters to proper
- ! thickness.
- !
- ! Other type vendors do not currently compensate for the fill algorithm
- ! and thus end up with undesirably heavy characters, which is
- ! particularly noticeable at small sizes.

- + The better the default letterspacing has been set, the fewer kerning
- + pairs are needed. In fact, an excessive number of kern pairs may be
- + the artifact of a poor letterspacing job.
- +
- + The typeface itself has a lot to do with which characters may benefit

- There are currently several printer manufacturers on the market with
- PostScript clones. To be viable, a PostScript clone must comply with
- ! the `red book' (PS Language Reference Manual).
-
- - In order to avoid paying royalties to Adobe, and because Adobe's Type 1
- - font format was originally preprietary, many PostScript interpreters use
- - some other font format. Sun uses F3, and some other vendors use
- - Bitstream's Speedo format, for example. The only real problem this causes
- - is that the widths of characters (the `font matrics') may vary from
- - Adobe's, so that programs that assume the Adobe character widths will
- - produce poor quality output. Bitstream fonts used to be particularly bad
- - in the early days, but they and most or all of the other vendors have

- There are currently several printer manufacturers on the market with
- PostScript clones. To be viable, a PostScript clone must comply with
- ! the `red book' (PS Language Reference Manual). The main problem the
- ! clones have is with fonts. Much of the font (and copy-protection)
- ! technology Adobe uses is undocumented.
- !
- ! The eexec operator is not defined and Adobe protects its operations
- ! as a trade secret. Without the eexec operator Adobe fonts cannot be
- ! decrypted. There are many other operators like eexec, such as the
- ! internal BuildChar routine, that are required for proper operation of
- ! Adobe fonts, and these operators are also held as trade secrets.
- ! Without these operators, the Adobe font data cannot be interpreted.
- !
- ! The clone problem can be approached from two directions. RIPS, a
- ! PostScript clone manufacturer, has reverse-engineered the eexec and
- ! other operators (including BuildChar and friends) and now sells a
- ! PostScript clone that is Adobe-compatible in all respects needed for
- ! proper interpretation of Adobe font data (Type 1 encrypted). Other
- ! companies are sure to follow. This is only important to users who
- ! have purchased or desire to purchase the Adobe/Linotype font library.
- !
- ! The other way to solve the font technology problem is to implement
- ! your own. This is the route chosen by Altsys, Bitstream,
- ! Kingsley/ATF, and various other vendors. Some of the technologies
- ! used by these companies have been listed and compared. All these
- ! vendors use Type 3 unencrypted fonts, but the similarities end there.
- ! The technologies implemented from one company to the next vary in
- ! source of artwork, precision of digitization, availability and types

- ! Apple's new System 7.0 will support a new format of outline font that

- Don Hosek offers the following insight into ligatures:
-
- ! Ligatures were used in lead type, originally in imitation of
- ! calligraphic actions (particularly in Greek which retained an
- ! excessive number of ligatures in printed material as late as the
- ! 19th century), but as typefaces developed, ligatures were retained
- ! to improve the appearance of certain letter combinations. In some
- ! cases, it was used to allow certain letter combinations to be more
- ! closely spaced (e.g., "To" or "Vo") and were referred to as
- ! "logotypes". In other cases, the designs of two letters were merged
- ! to keep the overall spacing of words uniform. Ligatures are provided
- ! in most contemporary fonts for exactly this reason.
- !
- ! Liam Quim makes the following observations:
- !
- ! The term ligature should only be used to describe joined letters in
- ! printing, not letters that overlap in manuscripts.
- !
- ! Many (not all) accents came from the practice of using a tilde or
- ! other mark to represent an omitted letter, so that for example the
- ! Latin word `Dominus' would be written dns, with a tilde or bar over
- ! the n. This is an abbreviation, not a ligature.
- !
- ! Most ligatures vanished during the 15th and 16th Centuries. It was
- ! simply too much work to use them, and it increased the price of book
- ! production too much.

- ! Ligatures were used in lead type, originally in imitation of
- ! calligraphic actions (particularly in Greek which retained an
- ! excessive number of ligatures in printed material as late as the 19th
- ! century), but as typefaces developed, ligatures were retained to
- ! improve the appearance of certain letter combinations. In some cases,
- ! it was used to allow certain letter combinations to be more closely
- ! spaced (e.g., "To" or "Vo") and were referred to as "logotypes". In
- ! other cases, the designs of two letters were merged to keep the
- ! overall spacing of words uniform. Ligatures are provided in most
- ! contemporary fonts for exactly this reason.
-
- [Ed: there is no "complete" set of ligatures.]

- -
- - CAUTION: While many Windows 3.1 users would like to have many
- - TrueType fonts at their disposal (and they are many available in the
- - PD) a word of caution. A large number (>50) TT fonts will slow down
- - your windows startup time. This occurs as every installed font is
- - listed in the win.ini file, and Windows has to go through the entire
- - file before starting up. While this may not affect most users, it
- - will especially affect users of CorelDraw!, so be warned.
